Given below are two statements:
Statement I: RSPM are those suspended particulate matters (SPM) whose aerodynamic diameter is more than 10 micron. Statement II: Fine particles are those SPM whose aerodynamic diameter is less than 2.5 micron.
In the light of the above statements, choose the most appropriate answer from the options given below:
- A.
Both Statement I and Statement II are correct
- B.
Both Statement I and Statement II are incorrect
- C.
Statement I is correct but Statement II is incorrect

Attempted by 10 students.
Show answer & explanation
Correct answer: D
RSPM refers to respirable suspended particulate matter with diameter less than 10 microns, making Statement I incorrect. Fine particles or PM2.5 have diameter less than 2.5 microns, making Statement II correct. Thus, Option 3 is the appropriate answer.
